GENERAL PRODUCT INFORMATION Through the advancement of internal fixation devices, the surgeon has been provided a means of aiding in soft tissue reattachment procedures. While the implants used are largely successful in attaining these goals, it must be recognized that no implant can be expected to withstand the activity levels and loads as would normal, healthy soft tissue after complete union occurs.

5

Each patient must be evaluated by the surgeon to determine the risk/benefit relationship. In using soft tissue fixation implants, the surgeon should be aware of the following: •

The correct selection and sizing of the implant is extremely important. Selection of the proper size, shape, and design of the implant increases the potential for success. The implants require careful seating and adequate bone support.

•

In selecting patients for surgery, the following factors can be critical to the eventual success of the procedure: 1. Patient’s occupation or activity. If the patient is involved in an occupation or activity which includes substantial lifting or muscle strain, the resultant forces can cause failure of the fixation, the device, or both. The implant will not restore function to the level expected with normal healthy bone, and the patient should not have unrealistic functional expectations. 2. Condition of senility, mental illness or alcoholism. These conditions, among others, may cause the patient to ignore certain necessary limitations and precautions in the use of the implant, leading to failure or other complications. 3. Foreign body sensitivity. Where material sensitivity is suspected, appropriate tests should be made prior to material selection or implantation.

DESCRIPTION The G-FORCE™ Tenodesis Screws are interference fixation screws for use in soft tissue reattachment procedures. The implants are available in various diameters and lengths and all are manufactured from PEEK-OPTIMA: a radiolucent, biocompatible polymer. Implants are intended for single-use only.

Infected, painful, swollen or inflamed implantation site

•

Bending, fracture, loosening, dislocation and migration of the implant may occur as a result of excessive activity, trauma or load bearing and may require revision surgery

•

Bone resorption or over-production

•

Allergic reaction(s) or inflammatory response(s) to implant material(s)

•

Migration of particle wear debris possibly resulting in a bodily response

•

Necrosis of the bone or tissue

•

Nonunion or delayed union

•

Embolism

E. WARNINGS AND PRECAUTIONS Following the instructions for use provided in product literature can minimize the potential for complications or adverse reactions with any implant. It is the responsibility of each surgeon using implants to consider the clinical and medical status of each patient and to be knowledgeable about all aspects of implant procedure and the potential complications that may occur. The benefits derived from implant surgery may not meet the patient’s expectations or may deteriorate with time, necessitating revision surgery to replace the implant or to carry out alternative procedures. Revision surgeries with implants are common. The patient’s mental status must also be considered. Willingness and/or ability

to follow post-operative instructions may also impact the surgical outcome. Surgeons must balance many considerations to achieve the best result in individual patients. IF EXCESSIVE LOADING CANNOT BE PREVENTED, AN IMPLANT SHOULD NOT BE USED. The main goal of surgery with this implant is to establish soft tissue to bone union. Abnormal or excessive forces could lead to delayed union, non-union, or failure of the implant. Abnormal force loading and subsequent wear may be caused by: •

Uncorrected instability

•

Improperly sized implant

•

Inadequate soft tissue support

•

Implant malposition

•

Excessive motion

•

Uncorrected or recurrent deformity

•

Patient misuse or overactivity

Proper fixation at the time of surgery is critical to the success of the procedure. Bone stock must be adequate to support the device. Some preventative measures to consider minimizing the potential for complications: •

Follow guidelines for indications and contraindications

•

Identify prior pathology

•

Stabilize collapse deformities

•

Bone graft pre-existing cysts

10

•

Use a properly sized implant

•

Avoid K-wires and sutures through the implant

Avoid flawing implant surfaces or excessive bending to minimize the potential for early fatigue failure. If complications develop, possible corrective procedures include: •

Implant removal

•

Bone grafting of cysts

•

Replacement of the implant

Clinical results depend on surgeon and technique, pre-operative and post-operative care, the implant, patient pathology and daily activity. It is important that surgeons obtain appropriate informed consent and discuss the potential for complications with each patient prior to surgery. This may include a review of alternative, non-implant procedures such as soft tissue reconstruction or arthrodesis. Recommendations Regarding Device Fragments •

Use medical devices in accordance with their labeled indications and Wright Medical Technology’s instructions for use, especially during insertion and removal.

•

Inspect devices prior to use for damage during shipment or storage or any out-of-box defects that might increase the likelihood of fragmentation during a procedure.

•

Inspect devices immediately upon removal from the patient for any signs of breakage or fragmentation.

•

If the device is damaged, retain it to assist with Wright Medical Technology’s analysis of the event.

11

•

Carefully consider and discuss with the patient (if possible) the risks and benefits of retrieving vs. leaving the fragment in the patient.

•

Advise the patient of the nature and safety of unretrieved device fragments including the following information: a. The material composition of the fragment (if known); b. The size of the fragment (if known); c. The location of the fragment; d. The potential mechanisms for injury, e.g., migration, infection; e. Procedures or treatments that should be avoided such as MRI exams in the case of metallic fragments. This may help to reduce the possibility of a serious injury from the fragment.

Concerning Magnetic Resonance Environments The devices described in this package insert have not been evaluated for safety and compatibility in the MR environment. The devices described in this package insert have not been tested for heating or migration in the MR environment. F. HANDLING AND STERILIZATION IMPLANTS The implants in this system are provided sterile. Implants in sterile packaging should be inspected to ensure that the packaging has not been damaged or previously opened. The implants should be opened using aseptic OR technique; they should only be opened after the correct size has been determined. This product is for single use only. An implant should never be re-sterilized after contact with body tissues or fluids.

12

Devices labeled for single-use only should never be reused. Reuse of these devices may potentially result in serious patient harm. Examples of hazards related to the reuse of these devices include, but are not limited to: significant degradation in device performance, crossinfection, and contamination. INSTRUMENTS Surgical instruments (and non-sterile implants) should be cleaned and sterilized according to the following parameters: Cleaning 1. Disassemble all components as per manufacturer instructions (if appropriate). 2. Rinse with cold tap water to remove gross contamination. 3. Bathe in an enzymatic detergent solution prepared per manufacturer directions for 5 minutes. 4. Scrub thoroughly with a soft brush and/or pipe cleaner; repeatedly flush any very narrow lumens with enzymatic detergent solution using a syringe. 5. Rinse with cold tap water for a minimum of one minute; use a syringe to repeatedly flush any very narrow lumens. 6. Bathe in a detergent solution prepared per manufacturer directions for 5 minutes. 7. Scrub thoroughly with a soft brush and/or pipe cleaner; repeatedly flush any very narrow lumens with detergent solution using a syringe. 8. Rinse thoroughly /flush with deionized / reverse osmosis (RO/DI) water. 9. Sonicate for a minimum of 10 minutes in an enzymatic detergent solution prepared per manufacturer directions. 10. Rinse thoroughly /flush with RO/DI water. 11. Dry with a clean, soft, absorbent, disposable cloth.

13

12. Visually inspect for cleanliness. All visible surfaces, internal and external, should be visually inspected. If necessary re-clean until it is visibly clean. Note: Brushes (i.e. pipe cleaners) could be used for cleaning most lumens, however, the use of a syringe to flush narrow lumens with diameters less than or equal to 0.041 inches is recommended. Sterilization The minimum recommended steam sterilization conditions for Wright reusable instruments (and non-sterile implants) are as follows: 1. Double wrap the component in an FDA-cleared CSR wrap or similar type non-woven medical grade wrapping material. 2. Autoclave according to the following parameters: Steam Sterilization Cycle Type Prevacuum 270 °F (132 °C)
